to flight can be drawnfrom the expressions derived in the preceding pages for thelift and wing-resistance of a cambered plane. In this chapterwill be considered the significance of the lift equation, andcertain relations between velocity and incidence that may bederived from it; wing-resistance… … WEIGHT Fig. 19. Lift-weight in horizontal flight. velocity V, and a coefficient of lift Kj^ that varies with theangle of incidence: Lift = L = Kl 5^2 For sustentation in horizontal flight, see Fig. 19, the lift mustbe just equal to the weight of the machine, including its load;we, accordingly, may…
